More of the West's small streams and wetlands would be protected by the Clean Water Act under an Obama administration proposal announced Wednesday. The new guidance would replace policies of the President George W. Bush administration and clear up some of the legal murkiness created by two US Supreme Court rulings that threw into question the reach of federal water pollution laws. The draft, which the administration described as a step toward adopting a formal rule, would broaden federal jurisdiction over small tributaries, seasonal streams and nearby wetlands. Industry spokesmen complained that the new guidance would add to their regulatory burden..."This clearly increases the federal environmental footprint on the landscape."
